Building a Cloudsdale Server

Building a Cloudsdale Server

By: Zeeraw & Lisinge

Step 1 - Setting Up Users

Add the user and it's home directory

root@cloudsdale:~# adduser zeeraw

Add .ssh folder to Users and change owner.

root@cloudsdale:~# mkdir /home/zeeraw/.ssh; chown zeeraw:zeeraw /home/zeeraw/.ssh

Add the user to sudoers.

root@cloudsdale:~# usermod -a -G sudo zeeraw

Add your pub_rsa to the .ssh directory on your user

Make so that you require no password for sudo

root@cloudsdale:~# nano /etc/sudoers

and change the line %sudo ALL=(ALL) ALL to %sudo ALL=(ALL) NOPASSWD: ALL

Fix Perl bug.

Add this to /etc/profile

export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8

And then run these commands root@cloudsdale:~# source /etc/profile; locale-gen en_US.UTF-8; dpkg-reconfigure locales

Step 2 - Building the essentials

Install build-essential

root@cloudsdale:~# apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev \
libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion imagemagick graphicsmagick libmagickcore-dev libmagickwand-dev

Install git

root@cloudsdale:~# apt-get install git-core

Install and configure NTP

root@cloudsdale:~# apt-get install ntp

root@cloudsdale:~# dpkg-reconfigure tzdata and Navigate into Etc -> UTC

Exit the ssh session and log into the server as your new account.

root@cloudsdale:~# exit -> ssh zeeraw@[subdomain].cloudsdale.org

Step 3 - Set up Ruby

Install RVM

zeeraw@cloudsdale:~# curl -L get.rvm.io | sudo bash -s stable

Then add the user to the RVM group

root@cloudsdale:~# usermod -a -G rvm zeeraw

Then install the correct ruby version

zeeraw@cloudsdale:~# rvm install 1.9.3-p125

Set default environment variables for ruby adding this to /etc/profile :

export RACK_ENV=production
export RAILS_ENV=$RACK_ENV
export RAKE_ENV=$RACK_ENV

Step 4 - Set up Monit

navigate to http://mmonit.com/monit/download/ find the latest source

root@cloudsdale:~# wget http://mmonit.com/monit/dist/monit-5.4.tar.gz
root@cloudsdale:~# tar zxvf monit-5.4.tar.gz
root@cloudsdale:~# cd monit-5.4

Install required pam headers

root@cloudsdale:~/monit-5.4# apt-get install libpam0g-dev

Configure

root@cloudsdale:~/monit-5.4# ./configure --enable-optimized
root@cloudsdale:~/monit-5.4# make
root@cloudsdale:~/monit-5.4# make install

Add this to /etc/init.d/monit :

#!/bin/sh

### BEGIN INIT INFO

# Required-Stop:     $remote_fs

# Default-Stop:      0 1 6

# /etc/init.d/monit start and stop monit daemon monitor process.

test -f $DAEMON || exit 0

if [ -f "/etc/default/monit" ]; then
     . /etc/default/monit
fi

ARGS="-c $CONFIG"

monit_not_configured () {
    printf "%b\n" "monit won't be started/stopped\n\tunless it it's configured"
    if [ "$1" != "stop" ]
        then
        printf "%b\n" "\tplease configure monit and then edit /etc/default/monit"
        printf "%b\n" "\tand set the \"startup\" variable to 1 in order to allow "
        printf "%b\n" "\tmonit to start"
    fi
    exit 0
}

monit_check_config () {
    # Check for emtpy config, probably default configfile.
    if [ "`grep -s -v \"^#\" $CONFIG`" = "" ]; then
        echo "empty config, please edit $CONFIG."
        exit 0
    fi
}

monit_check_perms () {
    # Check the permission on configfile. 
    # The permission must not have more than -rwx------ (0700) permissions.
   
    # Skip checking, fix perms instead.
    /bin/chmod go-rwx $CONFIG

}

monit_delayed_monitoring () {
    if [ -x $DELAY ]; then
      $DELAY &
    elif [ -f $DELAY ]; then
      echo
      echo "[WARNING] A delayed start file exists ($DELAY) but it is not executable."
    fi
}

monit_check_syntax () {
  $DAEMON -t 2>/dev/null >/dev/null
  if [ $? -eq 1 ] ; then
      echo "Syntax error:"
		$DAEMON -t
		exit 0
  fi
}


monit_checks () {
    # Check if startup variable is set to 1, if not we exit.
    if [ "$startup" != "1" ]; then
        monit_not_configured $1
    fi
    # Check for emtpy configfile
    monit_check_config
    # Check permissions of configfile
    monit_check_perms
	 # Check syntax of config file
    monit_check_syntax
}

case "$1" in
  start)
	echo -n "Starting $DESC: "
    monit_checks $1
	echo -n "$NAME"
	start-stop-daemon --start --quiet --pidfile /var/run/$NAME.pid \
		--exec $DAEMON > /dev/null 2>&1 -- $ARGS
   monit_delayed_monitoring
	echo "."
	;;
  stop)
	echo -n "Stopping $DESC: "
    #monit_checks $1
	echo -n "$NAME"
	start-stop-daemon --retry 5 --oknodo --stop --quiet --pidfile /var/run/$NAME.pid \
		--exec $DAEMON  > /dev/null 2>&1
	echo "."

	$0 stop
	$0 start

   monit_check_syntax
   ;;
  *)
	N=/etc/init.d/$NAME
	echo "Usage: $N {start|stop|restart|force-reload|syntax}" >&2
	exit 1
	;;
esac

exit 0

Then run

chmod +x /etc/init.d/monit

Add monit to autostart on boot

root@cloudsdale:/etc# update-rc.d -f monit defaults

Clone Monit configs from git

root@template:/etc# git clone git@github.com:IOMUSE/Cloudsdale-Monit.git monit
cd /etc
root@template:/etc# ln -s monit/monitrc

You can now visit monit at:
